 Rekeying (cryptography)

Rekeying in cryptography refers to the process of changing the cryptographic keys used for encryption and decryption. This is an important practice for maintaining the security of cryptographic systems, particularly for long-lived sessions or data. Here are some key aspects of rekeying: 1. **Security**: Over time, keys can become vulnerable due to potential exposure, advancing technology, or cryptanalysis. Regularly changing keys helps mitigate these risks.
